PURPOSE:To increase the friction between a coupling pillar and a side wall by a method in which a guide wall is constructed, a coupling pillar is driven along a construction guide in such a way as to cause it to cut into the side wall of a trench, and the tip is driven into the bottom of the trench. CONSTITUTION:A guide wall 2 is constructed and a trench 1 is excavated along the guide wall 2. A construction guide 7 is welded to an L-shaped steel 21 buried in the guide wall 2, and a coupling pillar 5 formed by placing space concrete into the concaved portion of a sheet pile 53 as a coupling steel material is erected along the guide 7. An iron bar cage 6 is then inserted into the trench 1 and connected to connecting iron bars 51, and concrete is placed. |
